Muaj ntau ntau dab rau ntawm qhov chaw ntawm lub luam Circuit Court board : liab qab PCB board (tsis muaj nto kev kho mob), OSP, Kub Cua Leveling (lead tin, ua-free tin), Plating kub, Immersion kub thiab lwm yam Cov no yog cov ntau pom.
Qhov txawv ntawm cov Immersion kub thiab Plating kub
Immersion kub yog ib txoj kev tshuaj deposition. Ib tug tshuaj txheej yog tsim los ntawm ib tug tshuaj oxidation-yuav txo tau cov tshuaj tiv thaiv. Feem ntau, lub thickness yog tus tuab. Nws yog ib yam ntawm cov tshuaj npib tsib xee-kub-kub txheej deposition txoj kev, thiab muaj peev xwm ua tau ib tug tuab kub txheej.
Kub plating siv cov hauv paus ntsiab lus ntawm electrolysis, kuj hu ua electroplating. Feem ntau lwm hlau nto kev kho mob kuj Electroplated. 
In the actual product application, 90% of the gold pcb board is the immersed gold pcb board,because the poor solderability of the plated circuit board is his fatal flaw, and it is also the direct cause of many companies to give up the gold plating process!
Immersion kub txheej txheem tso rau ntawm qhov chaw ntawm lub luam Circuit Court laug cam nrog ruaj nqaij daim tawv, zoo brightness, tus plating, thiab zoo solderability ntawm npib tsib xee kub plating. Yeej nws yuav tsum tau muab faib ua plaub theem: pre-kev kho mob (roj tshem tawm, micro-etching, ua kom, post-dip), npib tsib xee los nag, hnyav kub, post-kev kho mob (khib nyiab dej ntxuav, DI dej ntxuav, kom qhuav). Immersion kub thickness yog nruab nrab ntawm 0.025-0.1um.
Kub yog thov mus rau qhov chaw kho mob ntawm cov ntawv luam Circuit Court laug cam vim hais tias ntawm nws cov high hluav taws xob conductivity, zoo oxidation tsis kam, thiab ntev lifespan. Nws yog feem ntau siv raws li tseem ceeb boards, kub ntiv tes PCB boards, lwm yam yuav tsum muaj qhov sib txawv ntawm kub-plated rau cov laug cam thiab kub-raus boards yog tias kub plating yog ib qho nyuaj. Kub (puas resistant), kub yog mos kub (tsis hnav resistant). 
1. The crystal structure formed by Immersion Gold and Gold Plating is different. Immersion Gold is much thicker than Gold Plating. Immersion Gold will be golden yellow and yellower than Gold Plating (this is the method of distinguishing between gold plating and heavy gold plating.) a) Gold plating will be slightly white (nickel color).
2. Lub crystal qauv tsim los ntawm immersion kub thiab kub plating yog sib txawv. Immersion kub yog yooj yim rau weld tshaj kub plating thiab yuav tsis ua phem welding. Qhov kev nyuaj siab ntawm lub immerison kub lub rooj tsavxwm yog yooj yim rau kev tswj, thiab nws yog ntau conducive mus rau lub tsevneeg txheej txheem rau sib raug zoo cov khoom. Nyob rau tib lub sij hawm, vim hais tias kub yog ntau kub-plated tshaj kub, kub-fingered kub ntiv tes yog tsis wearable (shortcomings ntawm lub kub phaj).
3. Muaj tsuas yog npib tsib xee-kub rau hauv lub ncoo nyob rau hauv lub kub-raus PCB board .Tus teeb liab kis tau tus mob nyob rau hauv daim tawv nqaij nyhuv tsis cuam tshuam rau lub teeb liab nyob rau hauv cov tooj liab txheej.
4. Immersion kub yog ntau tuab tshaj cov kub plating siv lead ua qauv, tsis yooj yim los tsim oxidation.
5. Nrog zuj zus thov rau luam Circuit Court boardua cov neeg, kab dav, yov tau mus txog 0.1mm hauv qab no. Kub plating yog nquag kub luv luv Circuit Court. Qhov kub phaj tsuas muaj npib tsib xee thiab kub nyob rau hauv lub ncoo, ces nws yuav tsis yooj yim los tsim ib tug kub luv luv Circuit Court.
6. Cov immersion kub tsuas muaj npib tsib xee kub nyob rau hauv ncoo, ces tus solder tawv ntawm txoj kab yog ntau nrees sib raug zoo rau cov tooj liab txheej. Peb tes num yuav tsis cuam tshuam cov yov thaum ua nyiaj.
7. Rau cov siab yuav tsum ntawm cov PCB board, flatness yuav tsum yog zoo dua, cov kev siv ntawm immersion kub , immersion kub feem ntau tsis tshwm sim tom qab lub rooj sib txoos ntawm cov dub lev phenomenon. Lub flatness thiab kev pab cuam lub neej ntawm lub kub phaj yog zoo dua hais tias ntawm lub kub phaj.
Yog li ntawd tam sim no Thaum feem ntau factories siv cov immersion kub txheej txheem los mus tsim kub PCB board .Tiam sis, cov kub-raus txheej txheem yog kim kim tshaj kub-plating txheej txheem (ntau kub cov ntsiab lus), yog li ntawd muaj tseem muaj ib tug loj tus naj npawb ntawm cov uas tsis muaj nqi khoom siv kub-plating dab (xws li tej thaj chaw deb tswj panels, qho khoom ua si rau cov laug cam).
